Fixes #2465 - Simplify/Enforce LayoutStyle.Absolute when X, Y, Width, and/or Height are null or Absolute() (#2467)
* Merged v2_develop; updated API docs * Code cleanup * Fixed code that was using Dim/Pos before IsInit * Fixed ComboBox using Bounds before IsInitalized and grabbing focus when it shouldn't * Fixed ComboBox tests. Fixed FileDialog * Fixed all !IsInitalized warnings * Fixed AllviewsTester * Fixed CharMap scenario * Fixed ColorPicker (hack) * Fixed CoputedLayout and Csv Editor * Imrpoved warning * Fixed more warnings * Fixed GetTextFormatterSizeNeededForTextAndHotKey * Fixed AllViewsTester * AllViewsTester code cleanup * AllViewsTester code cleanup * AllViewsTester fixed for realz * Decided Fill was better than Percent for default
